ENGINE OPERATION
TNV Operation Manual 55
COLD START DEVICE
• The Cold Start Device on direct injection
models improves engine starting at lower
temperatures.
• If the engine cooling system temperature is
below 41°F (5°C), the Cold Start Device
automatically advances the fuel injection timing
and slightly increases the fuel injection volume.
• The engine idle speed will be slightly elevated
for approximately the first 5 minutes of
operation.
• When the Cold Start Device is activated, you
may notice a slight increase in the amount of
exhaust smoke, this is normal.
• NEVER engage the transmission or PTO while
the Cold Start Device is activated or
unexpected movement of the machine may
result.
CHECKING THE ENGINE
DURING OPERATION
A
WARNING
0000006en
SUDDEN MOVEMENT HAZARD!
• Allow the engine to warm-up for at
least 5 minutes to allow the engine idle
speed to return to normal before
engaging the transmission or any PTO
attachments. Engaging the
transmission or PTO at an elevated
engine speed could result in an
unexpected movement of the
equipment.
• Failure to comply could result in death
or serious injury.
CAUTION
0000010en
Make sure the engine is installed on a
level surface. If a continuously running
engine is installed at an angle greater
than 30° (in any direction) or if an engine
runs for short periods of time (less than
3 minutes) at an angle greater than 35°
(in any direction) engine oil may enter
the combustion chamber causing
exessive engine speed and generate
white smoke. This may cause serious
engine damage.
CAUTION

New Engine Break In:
• On the initial engine start-up, allow the
engine to idle for approximately 15
minutes while you check for proper
engine oil pressure, diesel fuel leaks,
engine oil leaks, coolant leaks, and for
proper operation of the indicators
and / or gauges.
• During the first hour of operation, vary
the engine speed and load on the
engine. Short periods of maximum
engine speed and load are desirable.
Avoid prolonged operation at
minimum or maximum engine speeds
and loads for the next 4 to 5 hours.
• During the break-in period, carefully
observe the engine oil pressure and
engine temperature.
• During the break-in period, check the
engine oil and coolant levels
frequently.
CAUTION

NEVER engage the starter motor while
the engine is running. This may damage
the starter motor pinion and / or ring
gear.
